Cold press machines are essential in the plywood manufacturing process, especially during the pre-pressing stage to stabilize glued veneer layers before hot pressing. Based on the structure and pressing mechanism, cold press machines are generally categorized into top-mounted and bottom-mounted types. Each has its own advantages and is suitable for different factory layouts and production needs.

In a top-mounted cold press machine, the hydraulic cylinders are installed above the upper platen. When activated, the top plate moves downward to compress the plywood layers placed on the stationary lower plate. This design is traditional and widely used across the plywood industry due to its strong pressing stability and ease of maintenance. Since the cylinders and hydraulic system are located on top, they are more accessible for inspection and repair. Additionally, the downward pressing movement provides uniform pressure and is less likely to cause displacement of the plywood during the pressing process.

On the other hand, a bottom-mounted cold press machine features hydraulic cylinders installed beneath the lower platen. In this setup, the bottom plate rises to press the plywood against a fixed upper plate. This structure is especially useful in factories with height limitations, as it eliminates the need for a tall overhead frame. Bottom-mounted designs also offer a more open and clean upper workspace, which is beneficial for automatic loading systems or conveyor integration. However, due to the upward pressing motion, these machines require precise alignment and high-quality guiding systems to ensure uniform pressure and to prevent misalignment of materials.

Another consideration is maintenance. In bottom-mounted systems, the cylinders are located below the working table, which can make access for repairs more difficult and may require lifting or disassembly. In contrast, top-mounted machines allow easier servicing since their hydraulic systems are positioned higher and more visible.

In summary, top-mounted cold press machines are better suited for operations prioritizing stability, ease of maintenance, and traditional setups. Meanwhile, bottom-mounted machines are ideal for space-saving layouts, automation compatibility, and applications where overhead clearance is limited. Choosing between the two depends on your factory space, production volume, and workflow preferences.
